CARRIAGE LOCK

Slide the carriage lock lever to the left to lock the carriage in

place. Slide the lever to the right to release the carriage. On

some models, the carriage lock is a thumb screw on the right

side of the carriage. Tighten to lock, loosen to release.

CAUTION: Hold the crank lever or motor head whenever

releasing the carriage lock. It could slam down causing

possible injury or damage to the bit or machine.

REDUCTION GEARING

On the larger size stands, QDS-500,

QDS-800, there are two crank spindles:

one for standard cranking and one for reduced gear ratio

cranking. The reduced gear ratio allows the operator

to drill with greatly reduced effort when using large

diameter core bits. To switch from standard to reduced

gear ratio cranking, simply remove the crank handle

from the main spindle and connect to the forward spindle

on the left side.

ADJUSTING THE DRILLING STAND GUIDANCE

Loose guidance will cause the bit to run out-of-true

and result in poor performance, sticking and possible

damage to the bit. If the rollers can be turned by hand

with the carriage locked, they are too loose.

To adjust the guidance, the two guide rollers on the left

side are on eccentric shafts. Turn the eccentric roller

axle bolt until the clearance is taken up on each roller

in turn. Turn just enough so that the roller cannot be

turned by hand. Now test the tightness of the carriage by

cranking it up and down. There should be no free-play,

yet no binding throughout its travel.
